[英]How to outline the selected row with transparent selection color in WPF DataGrid?
Something that looks like this:看起来像这样的东西:
I don't want to change the background or foreground color on selection, only outline the selected row.我不想在选择时更改背景或前景色,只勾勒出选定的行。
Is this possible in WPF?这在 WPF 中是否可行? I only see Winforms on SO.
我只在 SO 上看到 Winforms。
Ok so I added it to my existing resources, so now my XAML code's resources is like this:好的,所以我将它添加到我现有的资源中,所以现在我的 XAML 代码的资源是这样的:
<Window.Resources>
<local:NullImageConverter x:Key="nullImageConverter"/>

</Window.Resources>
Final result looks like this:最终结果如下所示:
So it still uses the background color as set by the alternating colors, and the separator style columns still show up, not sure if there is a way to fix those.所以它仍然使用由交替的 colors 设置的背景颜色,并且分隔样式列仍然显示,不确定是否有办法解决这些问题。
You have modify DataGridRow
style.您已修改
DataGridRow
样式。 Add trigger when IsSelected
is true and set BorderBrush
and BorderThickness
.当
IsSelected
为 true 并设置BorderBrush
和BorderThickness
时添加触发器。
<Style TargetType="{x:Type DataGridRow}">
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="BorderBrush" Value="Red" />
<Setter Property="BorderThickness" Value="1" />
</Trigger>
</Style.Triggers>
</Style>
Then modify DataGridCell
style.然后修改
DataGridCell
样式。 Add trigger when IsSelected
is true and set Background
and BorderBrush
to Null
.当
IsSelected
为 true 时添加触发器,并将Background
和BorderBrush
设置为Null
。 Also set Foreground
color otherwise Foreground
will be changed when you select a row.还要设置
Foreground
,否则当你 select 一行时, Foreground
会改变。
<Style TargetType="{x:Type DataGridCell}">
<Setter Property="Foreground" Value="Black"/>
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Background" Value="{x:Null}"/>
<Setter Property="BorderBrush" Value="{x:Null}"/>
</Trigger>
</Style.Triggers>
</Style>
You can write a style for DataGridRow.您可以为 DataGridRow 编写样式。 something like this.
像这样的东西。 you can add this style to App.xaml or resource in the window on anywhere you want.
您可以将此样式添加到 App.xaml 或 window 中的资源中您想要的任何位置。
<Style TargetType="{x:Type DataGridRow}">
<Setter Property="BorderBrush" Value="LightGray" />
<Setter Property="BorderThickness" Value="1" />
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="BorderBrush" Value="Red" />
<Setter Property="BorderThickness" Value="2" />
</Trigger>
</Style.Triggers>
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black" />
</Style.Resources>
</Style>
